Trying to setup my modem for wireless network. I change SSID to something different, tick the WPA box and then supply a HEX String for password. Click apply, log out and then reboot the modem. upon reboot settings have changed back to D-Link with no security !! any ideas ?

Hi, the firmware in these things is odd, it does not prompt you to save, I think you need to change the settings, then before rebooting you must go to Tools (top tab) then System (side tab) and click Save settings are reboot otherwise it does not remember changes.
